Abstract

The invention provides a unilateral external-hanging-type enclosed fire prevention system, and belongs to the field of underground engineering disaster prevention. An I-shaped mounting bracket is mounted on a cabin plate through expansion bolts, one side of the I-shaped mounting bracket is connected with the bolt connection end of a unilateral external-hanging-type enclosed fire prevention plate,and the other side of the I-shaped mounting bracket is connected with the plug end of the unilateral external-hanging-type enclosed fire prevention plate; the unilateral external-hanging-type enclosedfire prevention plate connected at the bolt connection end is mounted before the unilateral external-hanging-type enclosed fire prevention plate connected at the plug end. The unilateral external-hanging-type enclosed fire prevention system has the advantages of good fire prevention performance, good stress performance, quickness and convenience in mounting, easiness in replacement, effective full coverage on portions with poor fire prevention performance, significantly improved fire and disaster prevention performance, and capability of effectively reducing casualties and economic losses inthe event of a fire of an underground structure.

Description

technical field [0001] The invention relates to the field of disaster prevention in underground engineering, and specifically relates to a single-side external-mounted closed fire prevention system. Background technique [0002] With the continuous growth of urban population, the development and utilization of underground space is extremely important. Because the development and use of underground space has many advantages in solving a series of problems caused by urbanization, such as transportation, environment, and ecology, especially for many large and medium-sized urban centers in my country where land use is very tight. Therefore, in recent years, underground structures have developed rapidly in my country, and many subways and underground complexes have been built one after another. However, due to the very closed spaces of underground complexes and subways, and the large logistics and fire loads, once a fire occurs, it will cause The smoke is very large, but the prog...
